Challenges to using ground based sense and avoid (GBSAA) for UAS operations

Abstract

Sense and Avoid systems must be clearly defined in terms of expected intended function - A well defined Concept of Operation is a good start. Ground Based Sense and Avoid systems may not support “collision avoidance” - May not represent a complete solution - If there's a functional gap, what is the safety impact and what mitigates the issue... what operational limitations. Trade between Traffic Display and Maneuver Guidance - Allocation of functionality to pilot or avionics. System Design, Sensors, Architecture - Requirements should drive your design. Sense and Avoid systems are “Aircraft Systems” and subject to aircraft safety substantiation methods - Quantitative safety analysis - Include the effects of Failures and False/Misleading information.
